This is not a flame, but the original Cray 1 (Serial Number 1), did
not have SECDED. It did have parity checking.

If you pay close attention to the line of machines he designed, (and 
the features they have and don't have) you can learn a lot about what
he thought would speed up or slow down his machines.
